LID FOR CAR-AXLE BOXES.

SPECIFICATION forming part of Letters Patent No. 570,374, dated October27, 1896. Application filed August 14, 1895. Serial No. 559,239. (Nomodel.)

To all whom it may concern:

Be it known that I, ALBERT O. BUCKIUS, a citizen of the United States,residing at-Chicago, county of Cook, in the State of Illinois, haveinvented certain new and useful Improvements in Lids for Car-Axle Boxes,of which the following is a specification, reference being had to theaccompanying drawings, forming a part of the same.

This invention relates to lids for the boxes of car-axles.

The object of the invention is to produce an axle-box lid having meansfor operatively supporting a removable i lid-closing spring upon theinner face of the lid, and in such manner that the lid is not pierced orconstructed with an opening through the same.

An essential fault of axle-box lids as heretofore made and used is thatthey have been pierced to aord bearings or passages for the lid-closingsprings, and hence dirt, sand, and other foreign material could enterthe boxes 1to the injury of the axles. Another fault lies in locatingthe lid-spring in part or whole on the outside of the lid; another inpoorly protecting the spring against breakage or dislocation and loss,and when the spring has been supported Wholly on the inner face of a lidthis has been accomplished by means inefiicient to properly support thespring, or such that the spring could not be readily removed and.reinserted or duplicated.

The invention consists of an axle-box lid having a pocket or bridgeformed therein and on the inner face thereof for receiving and holding alid-closing spring, said spring-carrying pocket not having a passagethrough the lid and having an opening only on the inner side of the lid,through which the spring can be easily inserted into the pocket andremoved from the same, said spring intertting laterally with the lidbyaprojection on one fitting a groove or recess on the, other, by whichthe spring is held from moving lengthwise toward the pivot of the lid,said recess and projection being opposite to the pocket or bridge andacting therewith to hold the spring in place.

In the drawings, Figure l is a side-elevation view of an axle-box thelid of which is constructed according to my invention. Fig.

2 is an end view of the same. Fig. 3 is acentral vertical section of thesame.

A represents the axle-box, which may be of any suitable construct-ion orform.

B is the lid of the box, and C is the bolt der, it being held by itslower end in the 6 5 pocket or bridge H, which is cast or otherwiseformed integral with the lid, and the opening from which is on the underside or under face of the lid, the pocket being otherwise wholly closedfrom direct communication with the exterior of the lid. This spring isloosely carried in the pocket, as shown in Fig. 3. The spring is formedwith a cross corrugation or projection I, adapted to engage acorrespondingly-shaped recess J in the outer walls of the lid oppositeto the bridge or pocket. The projection and recess serve to preventmotion of the spring upward toward the pivot portion of the lid, and thebridge or pocket serves to keep the recess and projection in engagement.Together these parts therefore constitute an eflicient lock for `thespring, enabling it to be put in place easily, holding it with greatsecurity, and putting upon the body of the lid at the engagement of theprojection with the recess the work of holding the spring from upwardlongitudinal displacement. Otherwise the walls of the pocket are withoutspecial form, so long as they are adapted to receive and hold thespring.

K is an inwardly-projecting' flange that fits to the edges of the wallsof the opening of the box to insure the tight closure of the latter whenthe lid is down.

Vith this form of lid and spring-supporting pocket the lid under thestress of its spring holds the box tightly closed and withoutpossibility of ingress of sand or dust, and the spring is removably yetsecurely held in place.

What is claimed as new is the lid being imperforate at the place of in-yteriitting, and liavingon tlieiuteiiorzi bridge 1o fitting ever the endof the spring .opposite to the recess and coacting therewith to hold thespring in place; substantially as described.
